MACHINE FO R PUNCHING JACQUARD CARDS.

SPECIFICATION forming part of Letters Patent No. 453,170, dated May 26, 1891. I Application filed January 21, 1890. $erial No. 337,649. (No model.)

To wZZ whom it may concern:

Be it known that we, JOSEPH IRISH and SAMUEL J BRIDEN, citizens of the United States, residing at Bridgeport, county of Fairfield, State of Connecticut, haveinvented certain new and useful Improvements in Machines'for Punching Jacquard Cards, fully described and represented in the following specification and the accompan yin g drawings, forming a part of the same.

Our invention relates to machines for punching Jacquard cards, its general object being to improve the construction of such machines, rendering them more convenient for use and more rapid and efficient in operation. In machines of this class as heretofore constructed the selecting mechanism by which the desired punches are locked or otherwise rendered operative has been actuated for different points upon the pattern for which cards are to be punched by other means than a mechanical reading of the pattern. The method in most general use consists in providing a key to the pattern corresponding with the arrangement of the punches and selecting mechanism and then selecting and actuating successively the parts of the selecting mechanism indicated by the key as corresponding to the points of the pattern for which the cards are to be punched, this process consuming much time and being especially liable to error.

It is one of the specific objects of our invention to provide means whereby the selecting mechanism of the punching-machine may be actuated directly from a reading of the pattern, and we attain this object and greatlyincrease the accuracy and speed of the machine by providing a tracing mechanism connected to the selecting mechanism by suitable devices, so that the movement of the tracing mechanism in reading or following the pattern from one point to another for which cards are to be punched positions the selecting mechanism to determine what punches shall be rendered operative.

Another object of our invention is to provide a machine which by a slight adjustment shall be adapted for use either asa producing or arepeating machine.

A further object is to provide an improved means for securing a positive return of the needles and stop-rods and avoiding the use of springs for returning these parts to position.

WVith these and other objects in view our invention consists, primarily, in the combination, with a punching-machine of the class described and its selecting mechanism, of a tracing mechanism for determining the punches to be selected, and in various constructions and combinations of parts, which will be more particularly described in the specification and pointed out in the claims.

The machine herein shown and described has been constructed and is especially de signed for perforating cards for use in embroidering-machines of theclass shown and described in Letters Patent No. 407,352, granted to Joseph Irish July 23, 1889, and a reference is herein made to that patent for a fuller understanding of the purpose of the details of construction of our machine. It will readily be seen, however, that theinvention is of general application in Jacquardcard-punching machines, and that the construction of machines embodying the invention 'will differ widely in accordance with the class of mechanism for use in which cards are to be produced. In the patent above referred to the tambour-frame may move in any direction in a single plane and within certain limits to any extent, the direction and extent of movement of the frame being determined by a Jacquard mechanism employing the usual series of perforated cards. To control the various movements of the tambour-frame, these cards are provided with two series of perforations for each end of the card, one series determining the direction and the other the extent of movement of the frame, and the perforations at one end of the card controlling the upward and downward movements and their length and those at the other end the right and left movements and their length. For the production of these perforated cards it is necessary, therefore, to provide at each end of the card punches for the perforations, determining thedirection and extent of movement of the tambour-frame, and these two series of punches at each side of the machine will be hereinafter referred to as the direction and extent punches.

For a full understanding of our invention a full description will nowbe given, reference ICO der, the latter being removed.

being had to the accompanying drawings, forming a part of this specification, in which like letters and figures of reference indicate like parts.

Fig. 23 is a view at right angles to Fig. 22. Figs. 241 and 25 are detail views of the mechanism for feeding the cards and for throwing the machine in and out of operation. Fig. 26 is a detail on the line 26 26 of Fig. 9. Fig. 27 is a detail on line 27 27 of Fi 10. Fig. 28 is a detail hereinafter referred to.

Referring now to Figs. 1 to t, the base A of the tracing end of the machine has mounted upon ita carriage B, supportingapattern-carrier, which in this embodiment of the invention consists of a cylinder 3. The carriage B consists of a suitable base-frame formed of side pieces 11 and cross-pieces 13, the former being provided with anti-friction wheels 12, moving upon rails 10 011 the base A, and has at each end supporting-standards 14, in which is mounted the shaft 15, carrying the cylinder 0. The cylinder 0 is shown as slotted to receive the end of the pattern P, and may be provided with an interior drum on which the pattern is reeled; or the pattern may be secured to the surface of the drum in any other suitable manner.

Supported on a standard D, fixed to the floor or to the base of the machine, preferably at the rear of cylinder C, is a tracer E, which consists in its simplest form of a fixed rod terminating in a point and adapted to indicate the point upon the pattern brought below it by the movement of the cylinder.

For the purpose of rotating the cylinder to move the pattern below the tracerE, the shaft 15, carrying the cylinder, is provided at one end with a gear 18, with which engages a worm 10, carried on the end ofa shaft 20, which extends upward from the base of the carriage l3 and is mounted to rotate in bearings in a cross-piece 13 and standard 14. This shaft is provided at its lower end with a bevel-gear 21, meshing with a similar gear 22, carried by a sleeve 35, splined to a shaft 23, extending longitudinally of the carriage and mounted in standards attached to the floor or base of the machine. This shaft 23 is geared through bevel-gears 24 with a transverse shaft 25, also supported from the floor or base, and provided at its front end with a sprocket-wheel 26, from which an endless belt 27 extends upward to a similar Wheel 28, carried by a short shaft provided with the handwheel F and mounted upon a standard 29 at the front of the machine. The sleeve is carried on shaft 23 in one direction during the movement of the carriage B by the gear 21 engaging gear 22, and a lug 30, depending from the carriage, encircles.the shaft 23 and carries the. sleeve in the opposite direction, retaining the gears in mesh.

For the purpose of securing accurate adnstment between this rotary movem entof the cylinder and the movement of the mechanism for positioning the selecting mechanism, I provide the shaft 20 with the following means of adjustment: The worm 19 is not attached directly to the shaft 20, but is carried by a sleeve 1, provided with lugs 2,between which moves an arm 3 of a collar 4, adjustably secured to shaft 20 by a set-screw, as shown in Fig. 3. The lugs 2 are each provided with a set-screw 5, by which the movement of the arm 3 independently of the sleeve 1 is adjusted. The operation of this lost-motion-adj usting means will be described hereinafter in connection with similar devices in other parts of the machine.

For the purpose of moving the carriage B and cylinder 0 to the right or left a screwshaft 31 is provided, which is supported in standards secured to the floor or base of the
